So this is a fun little Macro I wrote. Especially if there are unaware desk operators that click it out of curiosity, because if they do, I will be Rolling On Floor Laughing Out Loud.
It clears the command line, then goes to cue out with a time of zero - taking everything to an immediate blackout, saves the show, runs my Macro 102 - which is just a group of all Moving Heads in my patch and tells them to Lamp Off, then it waits for 10 seconds before finally powering down the console, or exiting to the shell in Nomad.
